Here's a shot of a billboard currently up in Phoenix now, right off the 202 freeway. It's an advertisement for local jeweler Oliver Smith using the ink & brush piece I showed a few posts down. I first saw it from a plane window as we were landing at night, super cool spot..
Second thing is another book I have some stuff in, really cool book from Greece called Mural Art: Murals on Huge Public Surfaces Around the World by Kiriakos Iosifidis. Published by Publikat, includes everyone from Os Gemeos to Kent Twitchell to Diego Rivera.
